VIDEO: How to Spot a Liar

Lying has become so pervasive that researchers are studying this destructive behavior and author Ralph Keys says that we live in a "post-truth era."

Recently the American Psychological Association published a study showing that liars may experience a "cheater's high."

Science Today reported, "Even when there was no tangible reward, people who cheated felt better on average than those who didn't cheat, according to results of several experiments that involved more than 1,000 people in the U.S. and England."

In the following video Pamela Meyer describes clues that indicate when someone is lying. Meyer wrote the book Liespotting. Meyer is also CEO of Calibrate, a company that trains people to detect deception.
